Abstract

A system for providing vehicle location information or confirmation of remote entry system operation to a user. In one embodiment, a vehicle transceiver receives a wireless vehicle device function signal, and a vehicle controller generates a vehicle device control signal for use in operating a vehicle device in response. The vehicle controller also confirms operation of the vehicle device, and the vehicle transceiver transmits a wireless vehicle device function confirmation signal. A remote unit includes a transceiver for operation by the user for transmitting the vehicle device function signal and for receiving the vehicle device function confirmation signal. The remote unit also includes an indicator for providing an indication to the user confirming operation of the vehicle device, and a storage device for storing retrievable data representing the indication confirming operation of the vehicle device.

Claims

1. A system for providing vehicle location information to a user comprising:

a first transceiver to be located in the vehicle for receiving a wireless vehicle locator signal;

a first controller to be located in the vehicle and to be provided in communication with the first transceiver, the first controller for determining a signal strength of the vehicle locator signal, wherein the first transceiver transmits a wireless vehicle directional signal when a maximum signal strength of the vehicle locator signal is determined; and

a remote unit comprising,

a second transceiver for transmitting the vehicle locator signal, and for receiving the vehicle directional signal,

a second controller in communication with the second transceiver for generating an indicator control signal in response to the vehicle directional signal, and

an indicator in communication with the second controller for receiving the indicator control signal and providing an indication to the user in response thereto of a directional location of the vehicle relative to the remote unit.

2. The system of claim 1 wherein the second controller determines a signal strength of the vehicle directional signal and the indicator provides an indication of a distance between the vehicle and the remote unit based on the determined signal strength of the vehicle directional signal.

3. The system of claim 2 wherein the second controller comprises a received signal strength indicator.

4. The system of claim 2 wherein the indicator comprises a display and the indication comprises a directional arrow provided on the display.

5. The system of claim 4 wherein the indication further comprises numeric information provided on the display.

6. The system of claim 1 wherein the remote unit is for operation by the user.

7. The system of claim 1 wherein the indicator comprises a display and the indication comprises a directional arrow provided on the display.

8. The system of claim 1 wherein the indicator comprises a light emitting diode.

9. The system of claim 1 wherein the remote transceiver transmits the vehicle locator signal in a directed pattern.

10. The system of claim 1 wherein the first controller comprises a received signal strength indicator.
